Angiogenesis-Related Markers and Prognosis After Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy for Metastatic Colorectal Cancer

BACKGROUND: Patients presenting with peritoneal metastases (PM) of colorectal cancer (CRC) can be curatively treated with cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC). Angiogenesis is under control of multiple molecules of which HIF1a, SDF1, CXCR4, and VEGF are key players. We investigated these angiogenesis-related markers and their prognostic value in patient

Tumour regression grading after chemoradiotherapy for locally advanced rectal cancer : a near pathologic complete response does not translate into good clinical outcome

BACKGROUND: After preoperative chemoradiotherapy (CRT) for rectal cancer, clinically undetectable residual tumour deposits or pathologic lymph nodes may remain in the mesorectum.AIM: The aim of this study was to report histopathological effects of CRT and factors affecting outcome in a uniformly treated series of locally advanced rectal cancer (LARC) patients.METHODS: Between 2004 and 2008, 107 pa

Valuation of nature-based tourism using contingent valuation survey : evidence from South Africa

The increasing pressure within developing countries to focus on other national objectives has led to declining fiscal transfers for conservation. This paper assesses the potential for a typical large African park such as the Kruger National Park to generate additional revenue through an entrance fee hike in order to finance park operations. This is investigated by estimating international tourists

The future of dna barcoding : Reflections from early career researchers

Over the last two decades, the use of DNA barcodes has transformed our ability to identify and assess life on our planet. Both strengths and weaknesses of the method have been exemplified through thousands of peer-reviewed scientific articles. Given the novel sequencing approaches, currently capable of generating millions of reads at low cost, we reflect on the questions: What will the future brin

Time-dependent climate impact of utilizing residual biomass for biofuels—The combined influence of modelling choices and climate impact metrics

Understanding the influence of method choices on results in life-cycle assessments is essential to draw informed conclusions. As the climate impact of bioenergy remains a debated topic, the focus of this study is how the chosen temporal framing influences a comparison of the climate impact of utilizing residual biomass for biofuel production to that of leaving the biomass to decay. In order to com

What dominates heat transfer performance of a double-pipe heat exchanger

ZnO-water nanofluid in an inner pipe was experimentally investigated to improve the thermal efficiency of double-pipe heat exchangers. In this work, a 57.6% increase in the Nusselt number was obtained at Re = 14,340 when the ZnO-water nanofluid flowed through a helically corrugated tube. It was found that helical corrugation played a more important role in heat transfer enhancement than thermophys

A comprehensive treatment for peritoneal metastases from gastric cancer with curative intent

Recently, Peritoneal Surface Oncology Group International (PSOGI) developed a novel comprehensive treatment consisting of cytoreductive surgery (CRS) and perioperative chemotherapy (POC) for the treatment of peritoneal metastases (PM) from gastric cancer with curative intent. This article reviews the results of this treatment and verifies its indication. In this strategy, peritoneal cancer index (

Astrocytic reactivity triggered by defective autophagy and metabolic failure causes neurotoxicity in frontotemporal dementia type 3

Frontotemporal dementia type 3 (FTD3), caused by a point mutation in the charged multivesicular body protein 2B (CHMP2B), affects mitochondrial ultrastructure and the endolysosomal pathway in neurons. To dissect the astrocyte-specific impact of mutant CHMP2B expression, we generated astrocytes from human induced pluripotent stem cells (hiPSCs) and confirmed our findings in CHMP2B mutant mice. Our

School Principals’ Work Participation in an Extended Working Life—Are They Able to, and Do They Want to? A Quantitative Study of the Work Situation

The objective of this study is to increase the knowledge regarding school principals’ work situations by examining the associations between various factors and the school principals’ assessments of their ability or wish to work until 65 years of age or longer. The 1356 participating school principals in this study were aged between 50 and 64 years of age. Individual and work factors were evaluated

Benign prostatic hyperplasia/obstruction ameliorated using a soluble guanylate cyclase activator

Benign prostatic hyperplasia (BPH) is a feature of ageing males. Up to half demonstrate bladder outlet obstruction (BOO) with associated lower urinary tract symptoms (LUTS) including bladder overactivity. Current therapies to reduce obstruction, such as α1-adrenoceptor antagonists and 5α-reductase inhibitors, are not effective in all patients. The phosphodiesterase-5 inhibitor (PDE5I) tadalafil is

A Psychometric Evaluation of the Family Collaboration Scale and an Investigation of How the Close Family of Frail Older Patients Perceive the Collaboration with Healthcare Professionals on Acute Medical Wards at Hospitals in Sweden

The inclusion of family members in the acute care of older persons with complex needs results in better coordination of care and reduces the frequency and/or duration of rehospitalisation. Therefore, healthcare professionals need a tool to assess the collaboration with family members on acute hospital wards. The aims were to test the psychometric properties of the Swedish version of the Family Col

Modelling effects of climate change and forestry on weathering rates and base cation cycling in forest soils

Kemisk vittring kallas processen när mineralkorn löses upp och sönderdelas i molekyler eller atomer. Det är en viktig process, bland annat för att den frigör ämnen som skyddar marken från försurning och som fungerar som näringsämnen för växter. För de så kallade baskatjonerna kalium, kalcium, magnesium och natrium är vittringen i marken bland de största källorna. Framför allt de tre förstnämnda baBase cations are important in forest soils as nutrients for vegetation and protection against soil acidification. Today, base cations have been lost from soils through acidification and forest harvesting. With low levels in soils, temporary situations of deficiency could occur. One of the largest inputs of base cations to soils is minerals weathering, which makes it an important process. It is, ho

Support in the context of allogeneic hematopoietic stem cell transplantation - The perspectives of family caregivers

Background and aim: Family caregivers are often involved in helping recipients during allogeneic hematopoietic stem cell transplantation (allo-HSCT). Although the distress that often arises along the trajectory is evident to family caregivers, research on their perceptions of providing and receiving support is limited. The aim of this study was to explore family caregivers’ experiences of providin

Non-targeted analysis strategy for the identification of phenolic compounds in complex technical lignin samples

Lignin is the second most abundant biopolymer in nature and a promising renewable resource for aromatic chemicals. For the understanding of different lignin isolation and conversion processes, the identification of phenolic compounds is of importance. However, due to the vast number of possible chemical transformations, the prediction of produced phenolic structures is challenging, and a non-targe

Targeting Aquaporin-4 Subcellular Localization to Treat Central Nervous System Edema

Swelling of the brain or spinal cord (CNS edema) affects millions of people every year. All potential pharmacological interventions have failed in clinical trials, meaning that symptom management is the only treatment option. The water channel protein aquaporin-4 (AQP4) is expressed in astrocytes and mediates water flux across the blood-brain and blood-spinal cord barriers. Here we show that AQP4

Characterization of Onboard Condition Monitoring Techniques for Stator Insulation Systems in Electric Vehicles : A Review

The design of the stator insulation system for a traction machine used in electric vehicles is a challenge due to the tight requirements set on compact size, high dynamic stresses and a lack of automotive specific insulation standards. A poorly designed stator insulation can lead to safety issues and stator faults. Approximately, 20-30% of faults in traction machines are stator faults. In order to

Analyses of structural changes in ecological time series (ASCETS)

Assessing status of natural resources and ecosystem components is pivotal for management, where indicators or indices often are used as proxies of ecological state. Many indicators, however, lack reference points and are associated with sampling errors and environmental noise, limiting their usefulness in management. Here we present a method for assessing state changes in ecological indicator from
